I don't see them as digs actually. You work part time mindtrope and it clearly works for you and your family, but surely you must realise that your personal situation in having built up an excellent pension which you've managed to pay into while not working full time is exceptionally rare?
That's a fact, not an opinion, and women are massively disproportionally affected. You only need to do a quick google if you doubt it. A frightening percentage of women have inadequate pensions. Just as frightening are the misconceptions among many women- e.g. If they outlive their dh they'll 'inherit' his entire pension.
Private pensions have taken a massive hit since the recession, so again, unless you are in an extremely rare position of having built up a extremely good, protected pension, while not working full time, then you're probably going to be in for a shock.
The people I know who have the best pensions (not counting current pensioners) are those who've worked full time and have gold plated public sector pensions (even these are being affected now, but I mean the protected pot which people have accumulated)
Goodness knows, as a full time teacher at management level I found that even the very few years I worked 3 days a week when my kids were pre schoolers, has knocked a chunk off my pension; I'm just very relieved that I stepped back up to f/t as soon as my youngest started school.
I think this IS a big issue which predominantly affects women, and just because some individuals are in the rare position of working part time but having a great pension, doesn't mean we should ignore the fact that many women will be living out their old age without much financial security.
